To all whom it may concern.

Be it known that I, FRANK J. GILROY, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Heating Fluids Mechanically, of which the following is a specification.

My invention relates to heating fluids by forcing them through certain channels in solid bodies consisting of one or more pieces. The devices have proved effective, practically, in heating air; but other fluids may obthrough the air-heating body, which in this ittinstan iis a wluliar valve.

Figs. 3 and 4 show, respec y snetmeetin fag of two coacting parts of said valve? igsi iFarid o are views similar to Figs. 3 and 4, showing a different construction of the valve. 7 Fig. 7 is a fragmentary perspective view SlflOWlIlg' a different arrangement of the air-passages through the heating-body. Figs. 8 and 9 are respectively side view and section of a portion of a body having its passages arranged differently from those in any of the other forms. Fig. 10 is a section similar to Fig. 9, showing a slight modification of the form shown in the latter figure. Fig. 11 is aperspective view showing a broad passage between corrugated plates forming the main part of the heating-body.

In Figs. 1, 2, 3, and 4, A represents an aircompressor cylinder; B, a plun er therein; 0, an inlet-valve, and D the b0 y of a valve fixedin the wall of the cylinder to govern the escape of compressed air therefrom. A pipe E incloses the valve and conveys the escaping air to any desired point. This valve D is shown as consisting of a seat member F, fixed in the wall of the cylinder and having an axial rod G supported by arms H, extending inward from the walls of a large central opening I in the member Upon its outer side this member is recessed to receive a second member J, sliding upon the rod G 'and normally held in its seat in the member F by a spring K, whose tension may be re ulated by nuts L upon the free threaded en of the rod G. The working side of the member .J is accurately turned to cone pulley form, so

that this side of the member consists of a series of short cylindrical portions whose annular .endfaces are in planes perpendicular to the valves axis. Preferably each cylindrical portion is provided with a series of marginal notches M, formed by-refnoving a wedge-like portion, so that when the twoparts of the valve are together these notches form tapering passages. The notches in successive portionsare not in the same radial planes, so that any air passing in one notch must pass around the cylinder to enter another notch. The working side of the seat member is so formed that the end faces of the member J rest against corresponding parts of the seat when the valve is closed; but the diameters of the cylindrical parts of the seat are slightly greater than those of the corresponding parts of the part J If the spring be adjusted to press the member J toward its seat with mod erate force, theadvance of the plunger will overcome the force of the spring by urging :cornpressedgaiagamst the inner face of the member J ,therebfriaving thelattel s ightly from its seat and allowing air to pass and? cape into the pipe E from all sides of the valve. The air thus escaping willbe found to be highly heated, it being quite feasible to render the pipe E incandescent while holdin the hand upon the wall of the non-jackete compressor-cylinder.

In Figs. 5 and 6 I have shown a valve made up'of a series of superposed plates N N N N held together by bolts 0, each provided with numerous perforations and each having on its outer face a marginal rim P, holding its central portion at a slight distance from its neighbor, or, in the case of the outer plate, forming a seat for the moving valve member or cap Q, which, as before, is pressed to its seat by a spring Q The perforations in each plate are preferably out of registry increasing the number of plates. As shown, each plate is made up of beveled rings S, held foo IIO

Fig. 11 shows the heating-body as 'consisting of two corrugated plates U and side plates U, preventing the lateral escape of the air.

What I claim is 1. For heating fluids the combination with a body traversed by an attenuated passage whose walls are capable of relative lateral movement, of means for forcing fluid through said passage, and means for opposing yielding resistance to increasing the distance between its opposite walls.

2. For heating fluids, the combination with a body having an attenuated passage therethrough, of means for forcing fluid through said passage, and means for opposing yielding resistance to the escape of fluid from the mouth of said passage.

3. For heating fluids, the combination with a body having an attenuated passage, therethrough, whose cross-sectional area varies repeatedly, of means for forcing fluid through said passage.

4. For heatingfluids, the combination with r a body traversed by a narrow passage having forwardly-convergent portions, of means for forcing fluid through said passage.

5. For heating fluids, the combination with a body traversed by a capillary passage having broad parallel walls, of means for forcing fluid through said passage.

6. For heating fluids, the combination with a body traversed by a capillary passage having broad, walls changing in direction at successive points, and means for forcing fluid through said. passage.

7. For heating fluids, the combination. with a chamber having an exit adapted to permit a large stream of fluid to pass, of means for subjecting fluid in said chamber to pressure, and means for compelling all portions of the escaping stream to assume an attenuated form and pass between only slightly-separated passage-walls, whereby the contactsurface of the stream with the walls is made very great.

8. For heating fluids, the combination with a body channeled to form capillary paths which merge, of means for forcing fluid under pressure to pass along said paths through said body.

In testimony whereof I have signed my name to this specification in presence of two witnesses.
